High risk for virus-induced asthma exacerbations in children is associated with an IRF7lo immunophenotype, but the underlying mechanisms are unclear. Here, we applied a Systems Biology approach to an animal model comprising rat strains manifesting high versus low susceptibility to experimental asthma, induced by virus/allergen coexposure, to elucidate the mechanism(s)-of-action of the high-risk asthma immunophenotype.
There is now considerable evidence demonstrating that both prenatal and postnatal exposure to particular classes of microbial stimuli can provide beneficial signals during early life immune development, resulting in the protection against future inflammatory disease.
Children with asthma face serious mental health risk, but the pathways remain unclear. This study aimed to examine bullying victimisation and perpetration in children with asthma and a comparison sample without a chronic health condition, and the role of bullying in moderating psychosocial adjustment outcomes for those with asthma. A sample of children with and without asthma, and their parents, were recruited from hospital clinics.
Intrauterine growth restriction (IUGR) is associated with asthma. Murine models of IUGR have altered airway responsiveness in the absence of any inflammatory exposure. Given that a primary feature of asthma is airway inflammation, IUGR-affected individuals may develop more substantial respiratory impairment if subsequently exposed to an allergen. This study used a maternal hypoxia-induced mouse model of IUGR to determine the combined effects of IUGR and allergy on airway responsiveness.
The dramatic rise in allergic disease has occurred in tandem with recent environmental changes and increasing indoor lifestyle culture. While multifactorial, one consistent allergy risk factor has been reduced sunlight exposure. However, vitamin D supplementation studies have been disappointing in preventing allergy, raising possible independent effects of ultraviolet (UV) light exposure.
Most asthmatics would prefer workplaces, healthcare facilities, and environments that are fragrance-free, which could help reduce adverse effects
Our findings provide new insight into the molecular mechanisms operative at baseline in the airway mucosa in atopic asthmatic with natural aeroallergen exposure
We identified new asthma loci, found new associations at loci implicated in the comorbidity of asthma plus hay fever and confirmed nine known loci.
Identify entrenched areas of asthma management and treatment in which progress has stalled and to challenge current principles
To determine the contribution of RSV to the subsequent development of severe asthma in different subgroups of children at risk of severe RSV disease.
